What considerations are essential when connecting passkeys to our existing authentication and multi-factor authentication (MFA) systems?

When integrating passkeys into your existing authentication and MFA systems, it's crucial to ensure compatibility and a seamless user experience. Below are the key considerations to guide your integration process:

Passkey integration requires updating user interfaces to support passkey creation, authentication, and management.

• Standalone Passkey Authentication: Use passkeys as a single login method, replacing traditional methods like passwords and SMS OTPs.
• Passkey as a Second Factor: Incorporate passkeys into existing MFA workflows, ensuring compatibility with current token generation and verification processes.

• Credential Storage: Safeguard users' public keys, credential IDs, and metadata with an optimized database schema.
• WebAuthn Server: Choose a compatible library (e.g., SimpleWebAuthn, fido2-net-lib) for challenge generation and verification. Configure options like authenticator selection and user verification policies.

• Fallback Options: Provide alternative methods like OTPs for users unable to use passkeys.
• Cross-Platform Compatibility: Test extensively across browsers, devices, and operating systems to ensure a consistent experience.

• Encryption Standards: Encrypt stored credentials and manage data securely.
• Regulatory Adherence: Ensure compliance with regulations like GDPR or SOC.

By addressing these considerations, you can successfully integrate passkeys into your authentication and MFA systems, enhancing both security and user convenience.
